一般情况下,电冰箱的冷冻循环结构是由压缩机、冷凝器、膨胀阀和蒸发器组成。 In general, the structure of the refrigeration cycle of the refrigerator by a compressor, a condenser, an expansion valve and an evaporator composition. 压缩机将低温/低压的冷媒通过升温/升压转换为高温/高压的冷媒,冷凝器将从压缩机流入的冷媒通过外部气体进行冷凝。 Compressor low temperature / low-pressure refrigerant by heating / boost converter high-temperature / high-pressure refrigerant, the refrigerant from the compressor flows into the condenser is condensed by outside air. 由于膨胀阀的直径最小,将从冷凝器流入的冷媒进行减压膨胀。 Since the minimum diameter of the expansion valve, the refrigerant flowing from the condenser is depressurized expansion. 在蒸发器上,经过膨胀阀的冷媒在低压状态下蒸发,吸收箱体内的热量。 In the evaporator, the refrigerant through the expansion valve at low pressures and evaporated absorbing heat cabinets.

下面结合图对普通电冰箱的结构进行说明:如图1所示,电冰箱是包括冷冻室1、冷藏室和机械室5。 Below in connection with FIG general configuration of the refrigerator will be described: As shown in FIG. 1, a refrigerator 1 includes a freezing chamber, the refrigerating chamber and a machine chamber 5. 通过与蒸发器4进行热交换后的冷气直接流入冷冻室1,使冷冻室内的温度维持在摄氏零下18度。 Directly into the freezing chamber cold air by exchanging heat with the evaporator 41, the temperature of the freezing chamber maintained at -18 ° C. 冷冻室1的冷气流入冷藏室,使冷藏室内的温度维持在摄氏0-7度,冷冻室的后下方有机械室5。 The temperature of the cool air flowing into the refrigerating compartment the freezing chamber 1, so that the refrigerator compartment is maintained at 0-7 ° C, after the mechanical chamber 5 below the freezing chamber.

蒸发器4的上部安装有送风扇6和电机。 An upper portion of the evaporator 4 is attached to the blower fan 6 and motor. 送风扇6将经过蒸发器降温后的冷气强制循环到冷冻室,电机驱动送风扇,蒸发器前面安装了冷气管10。 The blower fan 6 through the cold air cooled forced circulation evaporator to the freezing chamber, motor-driven blower fan, cool air duct 10 is installed in front of the evaporator.

冷气管10是由分隔冷冻室内空间和蒸发器空间的内侧板7构成。 The cool air duct 10 is formed inside the partition plate freezer evaporator and the indoor space 7 spatial configuration. 内侧板7内有多个与冷冻室相通的冷气排出口11。 The inner plate 7 has a plurality of communicating with the freezing chamber cold air discharge port 11. 在冷气管10的下端有冷气吸入口13,经过冷冻室而升温的冷气通过冷气吸入口13重新流入到蒸发器4。 In the lower end of the cool air duct 10 has cool air inlet (13), through the freezing chamber cold air warmed by the cold air suction port 13 flows into the evaporator 4 again.
